Management of Late Presentation Rodenticide Poisoning

Immediate Stabilization and Assessment

• The American College of Cardiology recommends prioritizing supportive care over toxin identification, including airway management, hemodynamic support, and correction of critical vital signs, before confirming the specific rodenticide type, with a strength of evidence based on expert guidance from poison control 1, 2
• Contact poison control immediately for expert guidance in managing late-presenting rodenticide poisoning with established coagulopathy and bleeding 1

Antidote and Hemostatic Therapy

• The American Heart Association suggests monitoring for metabolic derangements requiring correction in patients with late presentation rodenticide poisoning 1

Management of Specific Complications

• EEG monitoring for non-convulsive seizures in patients with altered mental status is recommended, along with benzodiazepines for seizures or agitation, in the management of intracranial hemorrhage due to rodenticide poisoning 1

Critical Pitfalls to Avoid

• The American College of Medical Toxicology advises against delaying supportive care while awaiting rodenticide identification, as treatment must begin immediately based on clinical presentation, with a high strength of evidence 1
• The American Academy of Clinical Toxicology recommends against administering vitamin K prophylactically before coagulopathy is documented in patients without symptoms or significant exposure, and against using activated charcoal, ipecac, or gastric lavage in late presentations, as these are ineffective once absorption has occurred and may delay definitive care 1

Special Considerations

• Medical toxicology consultation is recommended for complex presentations of rodenticide poisoning, with a moderate strength of evidence 1
